    but sir i also know same method what u followed that method is given in schaums series book

    eduncle-logo-app

    because of this i am confused which is correct method

    eduncle-logo-app

    Its incorrrect . This formula will not be used here . This formula is used when region is bounded between x =f(y) and y axis .

    eduncle-logo-app

    But here region is bounded by x= 2 not y axis .
